The vehicle imaging device is attached to the rear of the vehicle so as to face the rear of the vehicle. The vehicle imaging device includes: a camera lens (15) facing the rear of the vehicle; a housing (14) that holds an imaging lens (15); and a rectifying protrusion (17).

Description
Technical Field
The present invention relates to a vehicle image pickup device that picks up an image of a rear side of a vehicle.
Background
In recent years, there have been increasing vehicles in which an imaging device for rear imaging is mounted in the rear of the vehicle. Such an imaging device is attached to a position below a trunk lid of a rear portion of a vehicle such that an imaging lens faces a rear portion of the vehicle. Therefore, when the vehicle is traveling, dust, muddy water, and the like that have been rolled up by the rear tires may be carried by the airflow toward the imaging lens (airflow toward the rear surface of the vehicle body after flowing along the upper and lower surfaces of the vehicle body) and blown onto the outer surface of the imaging lens. As a countermeasure, an image pickup apparatus including a cleaning mechanism for cleaning the outer surface of the image pickup lens is proposed (for example, refer to international publication No. 2014/010578).
The imaging device for a vehicle described in international publication No. 2014/010578 is configured such that a cleaning nozzle is provided in a housing that holds an imaging lens, and a cleaning liquid is ejected from a tip portion of the cleaning nozzle toward an outer surface of the imaging lens. The vehicle image pickup apparatus includes a cleaning liquid passage and an air passage, and guides a cleaning liquid in the cleaning liquid passage toward an image pickup lens by compressed air ejected from the air passage.
Disclosure of Invention
However, the vehicle imaging apparatus described in international publication No. 2014/010578 requires a cleaning liquid passage and an air passage for cleaning dirt on the imaging lens, and not only is the structure complicated, but also the entire apparatus is increased in size. Further, since equipment for guiding the cleaning liquid and the compressed air to the image pickup device is required, not only the product cost of the device alone but also the cost of equipment added to the vehicle increases.
An aspect of the present invention is to provide an imaging device for a vehicle capable of suppressing adhesion of dirt to an imaging lens with a simple structure that enables low-cost vehicle equipment.
A vehicle imaging device according to an aspect of the present invention is mounted on a rear portion of a vehicle so as to face rearward of the vehicle, and includes: an imaging lens that faces the rear of the vehicle; a housing that holds the imaging lens; and a rectifying protrusion protruding downward of the vehicle from a position below the imaging lens of the housing.
According to the above configuration, when an airflow including dust, muddy water, and the like that is raised by the rear tires passes below the imaging lens and flows into the front side of the housing during traveling of the vehicle, the airflow is separated by the rectifying protrusion that protrudes downward from the housing. As a result, a negative pressure is generated on the vehicle front side of the flow rectification protrusion, and an air flow containing dust, muddy water, and the like is introduced into the negative pressure. As a result, dust, muddy water, and the like in the air flow are less likely to adhere to the outer surface of the imaging lens.
The tip end portion of the rectification protrusion may be located on the vehicle rear side with respect to a tangent line of a lowermost point of a lens surface approximation curve of a fixed curvature that connects an uppermost point located on an outer side surface of the imaging lens, the lowermost point located on a lowermost side of the outer side surface of the imaging lens, and an intermediate point located at an intermediate position between the uppermost point and the lowermost point.
In this case, since the tip end portion of the rectification protrusion is located at the vehicle rear side of the tangent line at the lowest point of the lens surface approximate curve, the region where the negative pressure is generated during traveling of the vehicle (the region in front of the rectification protrusion) can be disposed at the vehicle rear side. Therefore, dust, muddy water, and the like that are intended to adhere to the outer surface of the imaging lens can be sucked out to the outside at a position further toward the vehicle rear side. Therefore, in the case of this configuration, it is possible to more favorably suppress the dust, muddy water, and the like in the air flow from adhering to the outer surface of the imaging lens.
The flow rectification protrusion may be substantially triangular in shape in a vehicle side view and substantially rectangular in shape in a vehicle rear view.
In this case, since the rectifying protrusion has a substantially triangular shape in a side view, the flow of the air is favorably peeled off at the tip of the rectifying protrusion. Further, since the rectifying protrusion has a substantially rectangular rear view shape, a negative pressure is likely to be generated in a wide range on the lower front side of the imaging lens. Therefore, with this configuration, it is possible to further suppress dust, muddy water, and the like in the air flow from adhering to the imaging lens.
The surface of the flow rectification protrusion facing the vehicle front side may be curved in a concave shape from above to below and toward the vehicle rear side.
In this case, when the vehicle is traveling, a stronger separation vortex is generated on the vehicle front side of the rectification protrusion, and a large negative pressure is likely to be generated that sucks dust, muddy water, and the like from the outer surface of the imaging lens. Therefore, with this configuration, it is possible to further suppress dust, muddy water, and the like in the air flow from adhering to the imaging lens.
The rectifying protrusion may be formed of a separate member that is detachable from the housing.
In this case, the flow regulating projection can be removed from the case to facilitate cleaning, and the flow regulating projection can be replaced with another flow regulating projection when damaged.
The rectification protrusion may be formed of an integral part integrated with the housing.
In this case, the flow rectification protrusion is an integral component with the housing, and therefore can be produced at low cost by die forming or the like.
A brim portion protruding rearward of the vehicle from an outer surface of the imaging lens may be disposed at an upper rear portion of the housing.
In this case, when the vehicle travels, the airflow flowing in the direction of the imaging lens from the upper rear side of the imaging lens is decelerated by contact with the brim of the rear portion of the housing. Therefore, dust, muddy water, and the like contained in the air flow are drawn into the negative pressure portion on the vehicle front side of the rectification protrusion in a decelerated state. Therefore, with this configuration, it is possible to further suppress the adhesion of dust, muddy water, and the like to the imaging lens.
According to the aspect of the present invention, the negative pressure generated in front of the rectification protrusion during the traveling of the vehicle can suppress dust, muddy water, and the like in the air flow from adhering to the outer surface of the imaging lens. Therefore, when the aspect of the present invention is adopted, the attachment of dirt to the imaging lens can be suppressed by a simple configuration that enables low-cost vehicle equipment.

Detailed Description
Hereinafter, embodiments of the present invention will be described based on the drawings. Note that an arrow FR indicating the front of the vehicle 1, an arrow UP indicating the upper side of the vehicle 1, and an arrow LH indicating the left side of the vehicle 1 are marked at appropriate positions in the drawings.
First, the first embodiment shown in fig. 1 to 4 will be described.
Fig. 1 is a side view of a vehicle 1 to which a vehicle imaging device 10 (hereinafter, referred to as "imaging device 10") of the embodiment is mounted.
The vehicle 1 is a sedan-type vehicle, and a trunk lid 3 that can be opened and closed is provided at a rear portion of the vehicle body. Further, a rear panel 4 of the vehicle body rear portion is provided with a concave portion 5 recessed in a concave shape toward the vehicle front side. The imaging device 10 of the embodiment is attached to the concave portion 5.
Fig. 2 is a side view of the imaging device 10 attached to the concave portion 5. In fig. 2, the concave portion 5 is schematically shown as being formed in cross section. Fig. 3 is a perspective view of the image pickup apparatus 10.
As shown in fig. 2 and 3, the imaging device 10 includes: a camera lens 15 facing the rear of the vehicle; a substantially cylindrical housing 14 which accommodates therein an imaging element and a substrate, not shown, and holds an imaging lens 15 at a rear end portion side; and a mounting base 13 that supports the base of the housing 14. The mounting base 13 can be mounted to the upper wall 5a of the concave portion 5 of the vehicle body rear portion.
In a state where the imaging device 10 is mounted on the vehicle body, the housing 14 is supported by the mounting base 13 so that the imaging lens 15 faces obliquely downward toward the rear side of the vehicle. A rectifying protrusion 17 protruding toward the vehicle lower side is provided to protrude at a position below the imaging lens 15 at the rear of the housing 14. In the case of the present embodiment, the rectification protrusion 17 is formed integrally with the housing 14 by a resin material.
The flow straightening projection 17 is formed in a substantially triangular shape (a substantially triangular shape having one side integrated with the case 14 and one top portion protruding downward) in a vehicle side view and in a substantially rectangular shape (a rectangular shape long in the vehicle width direction) in a vehicle rear view.
Fig. 4 is a schematic cross-sectional view showing a positional relationship between the imaging lens 15 and the rectifying protrusion 17.
As shown in fig. 4, an outer side surface 15s (a surface facing the vehicle rear direction side) of the imaging lens 15 is generally formed by a spherical surface of a fixed curvature in many cases. Therefore, as for the outer side surface 15s of the imaging lens 15, a lens surface approximation curve c of a fixed curvature as shown in fig. 4 can be considered.
The lens surface approximation curve c shown in fig. 4 is a virtual curve connecting the uppermost point p1 located at the uppermost position of the outer side surface 15s of the imaging lens 15, the lowermost point p2 located at the lowermost position of the outer side surface 15s of the imaging lens 15, and the intermediate point p3 located at the intermediate position between the uppermost point p1 and the lowermost point p2 of the outer side surface 15s of the imaging lens 15.
As shown in fig. 4, the rectification protrusion 17 protrudes downward such that the tip portion 17a of the rectification protrusion 17 is located on the vehicle rear side with respect to the tangent T at the lowest point p2 of the lens surface approximate curve c.
Further, a brim 20 protruding rearward of the vehicle from an outer surface 15s of the imaging lens is provided at a position above the imaging lens 15 in the rear upper portion of the housing 14. In the case of the present embodiment, the eaves 20 are formed integrally with the case 14 by a resin material. The brim 20 is formed to have a width (width in the vehicle width direction) larger than the diameter of the portion of the imaging lens 15 exposed to the outside of the vehicle.
Next, the flow of the air flow around the imaging device 10 when the vehicle is traveling will be described.
When the vehicle 1 travels, as shown in fig. 1, the traveling airflow flows rearward along the upper surface and the lower surface of the vehicle, and a part of the airflow changes its direction and flows into the rear surface side of the vehicle body. At this time, a part of the airflow a toward the vehicle rear surface side flows into the vicinity of the installation portion of the imaging device 10 in the vehicle body rear portion. Further, dust, muddy water, and the like that are rolled up by the rear tire Wr during traveling of the vehicle 1 may flow into the vicinity of the installation portion of the imaging device 10 in the vehicle body rear portion together with the airflow a toward the vehicle rear surface side.
As shown in fig. 2, the airflow a flowing into the vicinity of the installation portion of the imaging device 10 during vehicle traveling peels off the tip portion of the rectifying protrusion 17 protruding downward from the housing 14 of the imaging device 10, and generates a peeling vortex in the space in front of the rectifying protrusion 17. As a result, a negative pressure is generated in front of the rectification protrusion 17, and air at the lower edge of the rectification protrusion 17 is drawn in front of the rectification protrusion 17. As a result, dust, muddy water, and the like mixed in the air flow a are less likely to adhere to the outer surface 15s side of the imaging lens 15.
As described above, in the imaging device 10 according to the present embodiment, since the rectification protrusion 17 is provided so as to protrude toward the vehicle lower side from the lower position of the imaging lens 15 of the housing 14, it is possible to suppress adhesion of dust, muddy water, and the like in the air flow to the outer surface 15s of the imaging lens 15 by the negative pressure generated on the front side of the rectification protrusion 17 during traveling of the vehicle. Therefore, when the image pickup apparatus 10 of the present embodiment is used, adhesion of dirt to the image pickup lens 15 can be suppressed with a simple structure that enables low-cost vehicle equipment.
In the imaging device 10 according to the present embodiment, since the tip end portion 17a of the rectification protrusion 17 is located on the vehicle rear side with respect to the tangent T at the lowest point p2 of the lens surface approximate curve c having a constant curvature, the front region of the rectification protrusion 17 where negative pressure is generated during vehicle traveling can be disposed on the vehicle rear side. Therefore, dust, muddy water, and the like that are intended to adhere to the outer surface 15s of the imaging lens 15 can be reliably sucked out to the outside at a position further toward the vehicle rear side.
In addition, since the image pickup apparatus 10 of the present embodiment has the substantially triangular shape in the vehicle side view shape of the rectification protrusion 17, it is possible to satisfactorily peel off the airflow at the tip end portion of the rectification protrusion 17 and more reliably suck out dust, muddy water, and the like that are intended to adhere to the outer surface 15s of the image pickup lens 15.
In addition, in the imaging device 10 of the present embodiment, since the rectifying protrusion 17 has a substantially rectangular shape in the vehicle rear view, a negative pressure is easily generated over a wide range on the lower front side of the imaging lens 15, and it is possible to further suppress dust, muddy water, and the like in the airflow a from adhering to the imaging lens 15.
In addition, since the rectification protrusion 17 of the image pickup apparatus 10 according to the present embodiment is formed of an integral member integrated with the housing 14, it can be produced at low cost by resin molding or the like.
In the imaging device 10 of the present embodiment, a brim 20 that protrudes rearward of the vehicle from the outer surface 15s of the imaging lens 15 is provided in an upper rear portion of the housing 14 in a protruding manner. Therefore, when the vehicle is traveling, the speed of the airflow a flowing in from the upper rear side of the imaging lens 15 toward the imaging lens 15 can be decelerated by the brim 20, and dust, muddy water, and the like contained in the airflow can be easily introduced to the negative pressure on the vehicle front side of the rectification protrusion 17. Therefore, with this configuration, it is possible to further suppress the adhesion of dust, muddy water, and the like to the imaging lens 15.
Fig. 5 is a side view of the image pickup apparatus 110 of the second embodiment. In the embodiments described below, the same reference numerals are given to the same portions as those in the first embodiment, and redundant description is omitted. In the following embodiments, the eaves 20 of the first embodiment is omitted.
The basic configuration of the image pickup apparatus 110 of the present embodiment is substantially the same as that of the first embodiment, but the shape of the rectifying protrusion 117 provided to protrude below the rear portion of the housing 14 is different from that of the first embodiment. That is, the surface of the rectification protrusion 117 facing the vehicle front side in the present embodiment is curved in a concave shape from above toward below toward the vehicle rear side. As shown by the broken line in fig. 5, the flow straightening projection 17 of the first embodiment is formed in a linear shape in a side view on the surface facing the vehicle front side, but the flow straightening projection 117 of the present embodiment is formed in a curved line shape in a side view on the surface facing the vehicle front side and recessed toward the vehicle rear side.
In the imaging device 110 of the present embodiment, since the surface of the rectification protrusion 117 facing the vehicle front side is curved in a concave shape from above toward below toward the vehicle rear side, a stronger separation vortex is generated on the vehicle front side of the rectification protrusion 117 when the vehicle travels. Therefore, when the image pickup device 110 of the present embodiment is used, a large negative pressure is generated that sucks dust, muddy water, or the like from the outer surface 15s of the image pickup lens 15 during vehicle traveling, and it is possible to further suppress the dust, muddy water, or the like in the air flow from adhering to the image pickup lens 15.
Fig. 6 is a perspective view of the image pickup device 210 of the third embodiment.
The basic configuration of the imaging device 210 of the present embodiment is substantially the same as that of the first embodiment, but is different from the first embodiment in that the rectifying protrusion 217 protruding below the rear portion of the housing 14 is detachably attached to the housing 14. The rectification protrusion 217 is detachably attached to the housing 14 by, for example, clamping fixation, bolt fastening, or the like.
Since the rectification protrusion 217 of the image pickup device 210 according to the present embodiment is formed of a separate member that is detachable from the housing 14, the rectification protrusion 217 can be easily detached from the housing 14 and cleaned, and the rectification protrusion 217 can be easily replaced with another rectification protrusion 217 when damaged.
In the third embodiment shown in fig. 6, the rectification protrusion 217 is detachably attached to the outer surface of the housing 14 by clamping, fastening with a bolt, or the like, but the tip end portion of the rectification protrusion 317 locked inside the housing 14 may be protruded to the outside of the housing 14 as in the imaging device 310 of the modification shown in fig. 7. In this case, the rectifying protrusion 317 can be attached and detached by disassembling the case 14.
The present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the scope of the invention.
